' 1 Claim.

This invention relates generally to chair construction, and more particularly to an improved combined type ,of chair construction as used in theatres, public halls andgthe like.

provement upon the construction disclosed in the patent for Adjustable chair, issued to Wills, No. 1,237,850, such Wills'patent being lacking inasmuch as the chair assembly becomes unstable after considerable use due to the loosening of the adjustable joint connection at the rear of its several standards. Moreover, in the Wills construction, uncalled for expense is entailed due to its provision for vertically adjusting the backs of the several seats which, at the present time, is not necessary as the concrete floors, as now installed, are level and smooth in character. Hence no vertical adjustment is needed. The Wills structure is also deficient inasmuch as no means are provided for laterally adjusting the front leg of the standard, this providing for lateral adjustment of the arm member.

Now, in my improved construction, I eliminate the several above recited disadvantages as well as obtain additional advantages.

One of the primary objects of my invention is my construction whereby absolute rigidity may be obtained between the several standards and the said seat structures and I attain this by providing an integral bracket member which extends for a considerable distance along the side of the seat to which it is attached. This bracket member abuts against the edge as well as the back of the seat back and hence prevents any movement therebetween. One of these brackets is located at each side of the seat back.

Another object of my construction, which goes hand in hand with the preceding object, is the slotted foot construction of the rear leg of the standard, such construction permitting a lateral adjustment of the standard relative to the floor to which it is fastened and such permits the rigid connection between the upper part of the standard, the bracket members and the seat backs.

Yet another advantage may be obtained by slotting the front leg of the standard, such permitting the arm supported upon the standard to be positioned relative to the adjacent seats. For example, it is sometimes deemed advisable to place the arm on the extreme end of a series of seats at a slightly different corresponding angle than those on the remaining seats and my construction provides for this adjustment.

When seats of the above character are installed on floors, usually concrete, it is the practice to The present invention is deemed to be an im- Grand Rapids, Mich.

insert the holding bolts-or studs .intoithe floor and then bolt the standards to these protruding" studs. oftentimes the studs are incorrectlypositioned and my novel slotted construction of .the feet of the standards permits a correct fit. to be obtained with the studs. That is, the studs are usually. positioned in the floor :at points measured along the arcs of circles struck from the optical center of the stage and during the drilling of the concrete errors are often made which cause the studs, when in position, to be slightly ofiset along the arc of the said circle as regards their proper position. The lateral adjustment of the standards takes care of this difliculty.

Referring to the drawing,

Fig. 1 is a plan view, such showing a series of seats.

Fig. 2 is a rear elevation of a portion of Fig. 1.

Fig. 3 is a sectional view taken along the line 33 of Fig. 2, certain parts being omitted for the sake of clearness.

Fig. 4 is a View taken along the line i-4 of Fig. 2.

Fig. 5 is a sectional view illustrating the connection of the foot of a standard to a concrete floor.

Similar numerals refer throughout the several views.

Referring particularly to Figs. 1 and 2, H3 into similar parts dicates seat-portions and H back portions, such 0 being supported by standards.

These standards are positioned between the respective seat portions and each standard consists of a rear leg 20, a front leg 2! and intermediate connecting sections 22, the latter being shown in dotted lines in Fig. 4. The rear leg 20 of the standard terminates in a foot 23 which is slotted as indicated at 25 and 25, these slots receiving the studs 40 which are embedded in the concrete floor 4| as clearly shown in Fig. 5. The front leg 2| of the standard has a foot portion 27 which may be slotted as indicated at 23 and 29, these slots adjustablyreceiving other studs 40. Arms 3!) shield the top cross bar of the several standards as clearly shown in Figs. 1 and 2.

Referring now to Fig. 3, 50 indicates sheet metal brackets, these being fastened as at 5!, see Fig. 2, to the respective backs i I of the several chair units. The brackets have a portion 52 which snugly abuts against the edge portion of the seat back to thereby reinforce the same and terminates in a short portion which abuts against the flat face of the upper extension of the rear legs 20, see Fig. 3, the brackets having keyhole slots 53 to receive the holding screws or studs 54.

The lower end of each bracket is slotted as at 55 as is clearly shown in Fig. 2, this slot likewise receiving a holding stud 54.

Each seat portion I0 is hinged as indicated at 60 to the opposed standards and further aids in maintaining the structure in rigid relationship. From the description just set forth it will be seen that the standards may be placed in position upon the studs 40, the seats H1 bolted in position, then the backs ll slid downwardly to position and next the several securing studs or screws 54 are tightened whereby an extremely rigid structure is had. Next the studs 40, which hold the rear feet 23 of the standards in position have their securing means tightened downwardly, the slots 24 and 25 permitting an exact alinement of the several parts to be had and finally the fastening means for the front feet 21 are secured, the standards being properly alined before this last manipulation whereby the sets of arms 30 may be positioned in alternating divergent relationship.

From the above description it will be seen. that my device is economical to manufacture but yet will produce the several advantages as previously set forth.

Having thus disclosedmy invention, I claim as new and desire to secure the following combinations and elements by Letters Patent of the United States.

I claim:

An adjustable seat construction of the class described comprising, a plurality of standards, each standard having a rear surface slightly inclined from the vertical, a plurality of seats connected between the standards, backs located between the standards and means for fastening the backs onto the standards, said means comprising an integral bracket member attached to the back of the said back member and then extending along the edge of the back member for approximately one half of the vertical dimension of the back member whereby the back member is reinforced, said bracket having a portion extending toward and adjacent to the said standard member, said portionhaving a plurality of keyhole slots therein, and studs extending into said standard and adapted to receive said keyhole slots, the small portions of the keyhole slots snugly receiving the studs whereby lateral movement of the'backs relative to the standards is absolutely preventedby positive means and yet vertical adjusting movement between these two members is permitted;
